Other services that we offer are: A full (free!!) technical advice service, manufacturing to pattern (or drawing) those hard to find 'one off' parts, issuing dating certificates, DVLA original registration number retention, etc. In fact, for everything connected with S7 and S8 'Beams we're the people. We are the major source of Sunbeam spare parts and every part is made by us or specially for us. We endeavour to keep the spares stock ample and as inexpensive as we can. Obviously items that are cast involving moulds, need intricate machining, or are low volume will come out more expensive than items that are simpler to manufacture. We are, however, satisfied that our prices are competitive with modern, current motorcycle parts... and in many cases...cheaper!

Our catalogue is only a guide to the large stock of parts that we hold, or are in the process of manufacturing.... it does not list all the parts we keep. If you can't see it in the catalogue contact us, we may be able to help! Like you, we are keen enthusiasts... any problems you have, please call us. (Details on how to do this can be found on our 'Contact Us Now' page).

You can purchase a 'hard' copy of the catalogue and don't forget our 'Sunbeam Owners Workshop Manual' - these are a must for every enthusiast to have for reference! To order them, go to plate 10 of our 'online' catalogue and look up numbers 42 and 42a.

We very much look forward to hearing from you and hope that you enjoy perusing and regularly revisiting our secure interactive web site. Remember, here at Stewart Engineering we are dedicated solely to those superb Classic British Motorcycles, The S7 and S8 Sunbeams.
